Abstract

Processo per abbattere con un liquido l'ammoniaca contenuta in uno sfiato (in particolare negli sfiati degli impianti per la sintesi e la granulazione dell'urea), caratterizzato dal fatto che detto liquido è una soluzione acquosa di urea neutralizzata con un acido, il pH di detta soluzione neutralizzata essendo fra 5,0 e 7,0.Process for breaking down the ammonia contained in a vent with a liquid (in particular in the vents of urea synthesis and granulation plants), characterized in that said liquid is an aqueous solution of urea neutralized with an acid, the pH of said neutralized solution being between 5.0 and 7.0.
